Google directions service errors
If “Google directions service status:” error message appears, it means that the request to the Google directions service failed for some reason.

The list of error codes and their meanings can be found here.

Importance of correct date/time settings
If “Google directions service status: INVALID_REQUEST” error message appears, it could be due to an invalid setting of the current date and time on the device that is displaying the mirror interface.

This is due to the departureTime field of the drivingOptions field passed to the directions API being set to one minute from the current time, and google service checking that this timestamp is in the future. Basically I have using this cloning while developing an app for mobile app development company Using MMM-ModuleScheduler to configure the route refresh interval
You can use the MMM-ModuleScheduler module to trigger route updates using a certain schedule.
This may be useful for example to refresh the route more frequently in the morning and less frequently during the rest of the day, reducing the risk of exceeding the query limit set by google.

Just set “MMM-google-route/refresh” as the notification id in the notification_schedule configuration parameter of the module, e.g.

{
    module: 'MMM-ModuleScheduler',
    config: {
        notification_schedule: [
            // Refresh the route every minute from 7:00 AM to 8:00 AM, monday to friday
            { notification: 'MMM-google-route/refresh', schedule: '* 7 * * 1-5' }
        ]
    }
},
